Description
Features
- Superior corrosion resistance
Performs exceptionally well in marine, chemical, and industrial environments, ideal for outdoor, coastal, and architectural applications.
- High mechanical strength
Stronger than 5005 and 5052, suitable for medium-to-high-strength structural and decorative applications.
- Excellent formability and workability
Can be rolled, bent, stamped, and deep-drawn, suitable for medium-to-thin gauge processing and moderate forming.
- Smooth and uniform surface finish
Ideal for anodizing, painting, coating, embossing, or film lamination for both decorative and functional purposes.
- Good weldability
Compatible with TIG, MIG, and spot welding, ensuring reliable fabrication.
- Lightweight material
Low density helps reduce overall weight while maintaining strength and durability.
Typical Applications
- Marine and shipbuilding applications
Widely used for hulls, decks, superstructures, and marine fittings due to excellent corrosion resistance in seawater environments.
- Automotive and transportation parts
Suitable for truck panels, bus bodies, trailers, and structural components where medium-to-high strength and corrosion resistance are required.
- Chemical and industrial equipment
Applied in tanks, containers, pressure vessels, and protective panels for chemical and industrial environments.
- Architectural and building applications
Used for roofing, curtain walls, cladding, and decorative panels in outdoor and coastal environments.
- Heat transfer and thermal applications
Suitable for heat exchangers, cooling fins, and other components requiring good thermal conductivity.
- General fabrication and forming
Ideal for stamping, bending, rolling, and deep-drawing of medium-to-thin gauge sheets for structural or decorative purposes.
